The LTM4637 is a complete 20A output high efficiency switch mode step-down DC/DC μModule (power module) regulator. Included in the package are the switching controller, power FETs, inductor and compensation components. Operating over an input voltage range from 4.5V to 20V, the LTM4637 supports an output voltage range of 0.6V to 5.5V, set by a single external resistor. Only a few input and output capacitors are needed.Current mode operation allows precision current sharing of up to four LTM4637 regulators to obtain up to 80A output. High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, multiphase/current sharing, Burst Mode operation and output voltage tracking for supply rail sequencing. A diode-connected PNP transistor is available for use as an internal temperature monitor.The LTM4637 is offered in 15mm × 15mm × 4.32mm LGA and 15mm × 15mm × 4.92mm packages. The LTM4637 is available with SnPb (BGA) or RoHS compliant terminal finish. The LTM4637 is pin compatible with the LTM4627, a 15A DC/DC μModule regulator.

Demonstration circuit DC1872A features the LTM®4637EV, a high efficiency, high density switch mode step-down power µModule® regulator. The input voltage range is from 4.5V to 20V. The output voltage is jumper programmable from 1.0V to 1.8V with a rated load current of 20A. Derating is necessary for certain VIN, VOUT, frequency and thermal conditions. The DC1872A offers the TRACK/SS pin, allowing the user to program output tracking or soft-start period. The DC1872A allows the user to choose pulse-skipping mode or Burst Mode® operation for higher efficiency at light load conditions. The LTM4637 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC1872A.
